Officers from the Victoria County Sheriff Office gave a presentation on drugs commonly used by teenagers in the Crossroads area to Victoria school district administrators Monday afternoon.

A buffet of synthetic marijuana packets were spread across a table before principals, administrators and staff.

The county's special crimes unit sergeants J.T. Smith and Melissa Rendon led the presentation of illegal and illicit substances more than half of students in Texas consume before graduating, including LSD, cocaine and methadone.

"Meth is back on the rise again," Smith said. "These are the top drugs that you may see crop up on your campuses."

Elementary school students are increasingly involved in the drug trade, the sergeant warned.

"Things have changed dramatically in the last 20 years," Smith said. "Ecstasy is a big pedophilia drug."

Slides of multi-colored tablets with designer labels imprints were on display for the curious crowd of principals and administrators.

Vera Wang, Bart Simpson and four-leaf clovers were a few of the logos marking the illegal drugs.

"For some reason, we've noticed a lot of purple-colored tablets in Victoria," Rendon said. "These are very easy for kids to conceal."

As part of the sheriff's office new partnership with VISD, superintendent Robert Jaklich invited the officers to bring his staff up to speed on what kids are using nowadays.

"The idea came out of collaboration," Jaklich said. "This is a good way to teach our administrators how they can work with our school resource officers to identify students using drugs."

The sergeants said some of the drugs students are using have become increasingly difficult to detect.
